I'm suck with a problem regarding Flashbuilder 4.7. I have a project that I need to get going on a new machine. I have this project already working on a Mac but need to move to a new Windows machine. The problem when I try to run the project on the new machine I get an error which looks like this:

In the project's files there is a –app.xml file. One of the very first lines defines the namespace which is the API version for the app. 4.7 defaults to 3.1, IIRC, so somehow you've upgraded your AIR SDK to 3.4 but the destination machine is still on AIR SDK 3.1 which doesn't know about 3.4.

I'm a bit confused. In the FB preferences air 3.4 is listed as the version used. When I check for updated the updater reports that everything is up do date. In the Flex tab 4.6 is used. If I need to download an updated version of the air sdk is this the proper way to do it?
